PROBLEM TO BE SOLVED: To overcome the problem that water leakage is caused, because backfill sediment at a soffit of a main pipe of sewageworks cannot be sufficiently tamped, the main pipe is damaged by settlement, a branch pipe is displaced due to backfill before completion of curing, and poor bonding is caused by lack of the curing of an adhesive, in a conventional method for mounting the branch pipe. SOLUTION: A fixture for bonding the branch pipe for the sewageworks is used in processes comprising: a process (a) in which a hole 2 is provided in the main body 1 for the sewageworks; a process (b) in which the adhesive 5 is applied to a flange part 4 in which the branch pipe 3 is brought into contact with the main pipe 1, so that temporary placing can be carried out in such a manner that the hole 2 serves as a center; a process (c) in which the fixture is inserted into the main pipe 1 from the hole 2 of the branch 3 and framed from within, and in which a device is pulled up in such a manner that a pat 7 of a supporting point part 6 is applied to an inner surface of the main pipe 1 so as to serve as a reaction support; a process (d) in which a pressure part 10 is placed at an outer end of the branch pipe 3 and temporarily held by a washer 11, and in which a bolt 9 is tightened with a nut 12; and a process (e) in which after a lapse of time up to the completion of the curing of the adhesive 5, the nut 12 is loosened for removal of the fixture.
